SUMMARY

The discussion centers on the performance issues of a DC booster circuit powered by a GP 23A 12V battery. Users report a significant voltage drop in the battery when connected to the booster circuit, which outputs approximately 40V. Key questions raised include the energy rating of the battery in Amp-hours and the current drawn by the booster circuit. Understanding these parameters is crucial for optimizing battery life and maintaining voltage stability.

I use a 12V battery to power a DC booster circuit. After just a moment, my battery's voltage decreased, causing the booster circuit to also decrease its voltage. Is there any way to make the battery last longer without losing voltage? Thanks

What is the energy rating of your battery (in Amp-hours)? What current do you measure out of the battery when it is driving the boost circuit? What is the load of the boost circuit (output voltage and current)?

The output voltage of the booster circuit is about 40V, and I don't know what the energy rating of the battery is (I use a GP 23A 12V battery).
